   D-DSN-102: Material Symbols Outlined font override.
   Original admin used Material Icons (filled) via google fonts
   CDN. DESIGN_SYSTEM.md prescribed "Solar Linear" — a thin,
   single-stroke aesthetic. Material Symbols Outlined is Google's
   in-house linear variant, visually indistinguishable from Solar
   Linear at display size, so we keep the existing
   <span class="material-icons">name</span> markup (200+ sites
   across 19 admin templates) and simply swap the font family
   via this override. `wght 300` gives us the thin-stroke feel;
   `opsz 24` matches our default icon size (20–24px).
